Gene Editing Could Cure 15,000 Diseases

Scientists at MIT and Harvard have discovered two gene editing techniques to fix mutations that cause diseases like cystic fibrosis and Duchenne muscular dystrophy.

Both diseases, and about half all human genetic disorders, are caused by mutations in single letters in the human genome, in which an ‘A’ appears where there should be a ‘B.’

The newly-developed gene editing systems can target the smallest units of our DNA or RNA to undo the mutation that causes cystic fibrosis.

One system edits DNA in the genome itself, while the other targets RNA, which transports genetic messages for making proteins.

MIT and Harvard scientists have developed a new gene editing tool that can rewrite the mutation in the genome that causes inherited diseases like cystic fibrosis
